A 100‐GHz full 360° reflection‐type phase shifter using a balanced phase inverter
Microwave and Optical Technology Letters, 2020AbstractThis paper presents a 100‐GHz phase shifter capable of providing full 360° continuous phase tuning range in 55 nm CMOS technology. The phase shifter is based on reflection‐type phase shifter (RTPS), which has more than 180° phase shift and employs a 0°/180° phase inverter (PI).

Energy-efficient thermo-optic silicon phase shifter with well-balanced overall performance
Optics Letters, 2020Silicon photonic integrated circuits (PICs) show great potential for many applications. The phase tuning technique is indispensable and of great importance in silicon PICs. An optical phase shifter with balanced overall performance on power consumption, insertion loss, footprint, and modulation bandwidth is essential for harnessing large-scale ...

A Balanced Digital Phase Shifter by a Novel Switching-Mode Topology
IEEE Transactions on Microwave Theory and Techniques, 2013A balanced digital phase shifter by a novel switching-mode topology is proposed. A 3-bit balanced digital phase shifter is given as an example, the working bandwidth of which is from 2.3 to 2.7 GHz. The proposed 3-bit balanced phase shifter comprises two balanced loaded-line phase shifters (90° and 45°) and six twist-line broadband 180° phase shifters.

Compact microstrip balanced phase shifter with common-mode suppression
2020 IEEE Asia-Pacific Microwave Conference (APMC), 2020Balanced phase shifter (BPS) plays an important role in differential beamforming networks and phased array antenna systems due to the capabilities of differential-mode (DM) phase shift and common-mode (CM) suppression. The compactness of BPS also becomes highly demand for its benefit to miniaturize the system.

An I/Q active balanced harmonic mixer with IM2 cancelers and a 45° phase shifter
IEEE Journal of Solid-State Circuits, 1998To reduce DC offset caused by local-oscillator-signal self-mixing in a direct-conversion receiver, an active balanced harmonic mixer with second-order intermodulation (IM2) canceler was proposed, and a direct downconverter containing the mixer and a 45/spl deg/ phase shifter was fabricated on a BiCMOS chip.

Compact Tunable Phase Shifters on Screen-Printed BST for Balanced Phased Arrays
IEEE Transactions on Microwave Theory and Techniques, 2011Two designs for compact continuously tunable phase shifters are presented employing integrated ferroelectric varactors based on screen-printed barium-strontium-titanate thick film. The circuits are based on left-handed transmission-line topologies that allow to realize very compact modules.
